To date, theoretical studies concerning the Carbon Fiber Reinforced Polymer (CFRP) strengthening of RC beams with openings have been rather limited. In addition, various numerical analyses presented so far have effectively simulated the behaviour of solid beam strengthened by FRP material. In this paper, a two dimensional nonlinear finite element analysis is presented to validate against the la...

Accurate simulations of carbon fiber-reinforced plastic (CFRP) molding are vital for the development of high-quality products. However, such simulations are challenging and previous attempts to improve the accuracy of simulations by incorporating the data acquired from mold monitoring have not been completely successful. Therefore, in the present study, we developed a method to accurately predi...

This paper presents experimental research on reinforced concrete (RC) beams with external flexural and flexural–shear strengthening by fibre reinforced polymer (FRP) sheets consisting of carbon FRP (CFRP) and glass FRP (GFRP). The work carried out has examined both the flexural and flexural–shear strengthening capacities of retrofitted RC beams and has indicated how different strengthening arra...

It is well known that in the Non Destructive Testing/Evaluation (NDT/E) context, Ultrasonic Echoes (UEs) and Tests (UTs) are intensively exploited to identify and characterize defects in the Carbon Fiber Reinforced Polymer (CFRP). This paper examines the localization and the classification of defects in this material from a fuzzy geometrical point of view. In particular, starting from an experi...

Carbon fiber reinforced polymer (CFRP) is widely used in the lightweight design of high-speed trains due to its high specific strength. In order further reduce weight train body, it necessary study joining process and fatigue properties CFRP/aluminum alloys (CFRP/Al) structure. this work, CFRP plate 5083P-O aluminum were successfully connected by an induction brazing method. The optimum paramet...

Abstract Graphene and its related materials are increasingly applied in fiber‐reinforced polymers to tailor their material properties for high performance composites. Yet, the use of graphene derivatives that underwent a plasma functionalization process is not well understood. This study uses 1.50 wt.% unfunctionalized (rGO) or plasma‐treated reduced oxide with amine‐functionalities (frGO) an e...

This article presents results of an investigation that focuses on assessing bondline strength carbon/epoxy fiber reinforced polymeric (CFRP) precured strips embedded in concrete for near-surface-mounting (NSM) strengthening applications. In this study, experimental evaluation and nonlinear numerical analysis CFRP/concrete interfacial bond behavior are investigated. 15 pull-out tests were perfor...

In this paper, the applicability of the constant life diagram (CLD) methodology for fatigue strengthening of metallic members is described. The CLD methodology is a method that uses the combined effect of alternating stress, mean stress and material properties to predict the material life-time under high-cycle fatigue loading. The method could be used most efficiently to improve resistance to c...

In this study, we aim to investigate the effect of galvanic corrosion on mechanical properties aluminum-CFRP adhesive joints. Aluminum-CFRP, aluminum-aluminum, and CFRP-CFRP joint specimens were prepared. Subsequently, subjected accelerated aging treatment in a salt spray environment, tensile shear strength, transition failure surface deposition state components products with time quantitativel...

Carbon fiber reinforced polymer (CFRP) can be applied for bridge cables due to its excellent properties. As the important load-bearing structural component, real-time force monitoring of CFRP cable is required. This paper presents a new smart that combines self-sensing rods with embedded sensors and anchorage system using extrusion technology. By embedding optical (OF) coaxial Fabry-Perot inter...
